INSULATING AND PLASTER-H OLDING WALL AND CEILING COVERING.

I Application filed March 5, 1926. semi No. sasnREISSUED This invention relates to improvements in composition coverings designed for use particularly in forming interior and exterior walls, ceilings and partitions of building structures.

The object of the invention is to provide such coverings formed of felt or heavy paper that will act as non-conductors of heat and cold, and as sound deadeners; that are water proof, and are provided with a surface to which plaster may be directly applied, and to which it will rigidly adhere, thereby permitting walls, ceilings and partitions of buildings to be constructed without the use of the usual wood or metal lath and, if preferred, without the use of intermediate studding or posts.

The invention consists generally in the constructions and combinations hereinafter described and particularly pointed out in the claims.

in the drawings,

Figure 1 is a perspective view of a portion of an interior wall formed of our improved covering without any intermediate stu ding, and with plaster applied directly to the surface of said covering, a portion of the plaster being broken away to permit illustration of a portion of the surface of the covering;

Figure 2 is a detail sectional plan of a portion of the wall shown in Figure 1 with the laster omitted to illustrate how. the over. apping edges of the covering may be secured together; I

Figure 3 is a perspective view showing the covering nailed to vertical studding with the plaster applied to one surface of the sheets-only; I

Figure 4 is a detail sectional plan of the structure shown in Figure 3 illustrating the manner of securing the overlapping edges of the sheets by a s1ngle row of nails;

Figure 5 is a detail of the structure shown to one surface of the composition covering onl l igure 6 is a view illustrating how the sheets may be constructed with one edge adapted for an overlapping joint and the opposite edge for a butt joint;

Figure 7 is a detail showing .a single sheet with the asphalt layer applied to each surface thereof;

.Figure 8 is a detail sectional view show;

ing how two sheets may be secured together when not provided with the longitudinal flanges shown in Figure .6; and

Figure 9 is' a view similar to Figure 8 showing one ofthe sheets having a butt joint edge and the other a flanged edge.

In the drawings 2-2 represents sheets of what is known as dry or unsaturated felt, which is preferably composed of a mixture of vegetable and wool fiber, made by grinding up paper, rags and similar material. This material is preferably made in long sheets which are wound into rolls as the sheets are produced by the felting ma chine. The material is cellular in construction and forms excellent insulation against heat and cold and is also a non-conductor of sound.

.VVe preferably employ two sheets of like material and secure thev same to ether by placing'between them a layer of liquid asphalt 4: which not only binds the sheets together but forms a water proof coating between them. To the outer surface of one or both of the felt sheets, we also apply a coating of liquid asphalt 5. In Figure 2 we have shown the asphalt applied to both of the outer surfaces of the composite sheet. This arrangement will preferably be empioyed when the sheets are to be used for forming a partition or wall without intermediate studding, and tobe plastered on both sides, as indicated in Figure 1 of the drawing. Where the sheets are to be secured to spaced studding 6, as shown in Figures 3 and 4, the asphalt need be applied to only one surface as indicated in Figure 5.

In forming the composite sheets we preferably arrange each sheet so as to project at its edge a short distance beyond the edge of the conti uous sheet, thereby making a projecting fi ange 7 at each edge of each sheet (see Figs. 3 and 4). When the sheets are to be used without spaced studding, as

shown in Figure 1 of the drawing, the edges '1 of the sheets are overlapped, as shown in Figure ,2, and are secured together by staples 8, or by suitable nails or' cement. When the sheets are to be secured to spaced studding, as indicated in Figure 3, the overplapped edges of the sheets may bev nailed to the studding, a sin le row of nails being used and driven t rough the overlappe edges of the sheets as shown in Figure If preferred, the sheets may be overlapped, as described, so as to form a flange at each edge, as indicated in Figure 1, and then if preferred the sheets may be severed lengthwise as indicated in Figure 6, thereby forming two sheets, each having one edge adapted for a. butt joint and its opposite edge provided with the flanged edge already described. For forming inside walls and partitions, we may use a single sheet of felt and apply the liquid asphalt thereto, preferably to both faces of the felt, as shown in Figure 7. a

In building a wall or partition, if with out the use of studding, the sheets are extended from top to bottom of the space to be enclosedand the upper and lower'ends of the sheets are secured to horizontal strips .9 secured to the ceiling and flooring of the room, as shown in Figure 1. With such an arrangement the sheets will preferably be supplied with asphalt on both surfaces so that the plaster can be applied to both surfaces of the felt. The plaster will firmly adhere to the asphalt and to the felt sheet and will form a substantial and satisfactory partition without the use of studding or lath, the Vertical sheets with the asphalt on each surface and the plaster applied directly to the asphalt forming in itself a substantial partition or wall.

We ordinarily employ what is known as dry felt, which is a cellular material composed of a mixture of vegetable and wool fiber made by grinding up paper, rags and similar material.

It is not essential to have the flanges 7 on the edges of the sheets as the meeting edges of the sheets may be overlapped and staples or nails driven through the overlapping portions as shown in F1gure 8, or one flanged edge and one butt edge may be united as shown in Figure 9. While this will leave 8.

ridge in the surface, such ridge will be completely covered by the plaster which will in itself form a smooth surface firmly secured by the asphalt coating to the felt sheet.

\Ve do not confine ourselves to any particular size or number of sheets to be used, as such details may be varied in many ways, without departing from our invention.

We claim as our invention:

1. A plaster wall comprising in combination a plurality of sheets, said sheets bein united by a layer of asphalt, with a layer 0 asphalt upon the outer faces of the sheets and plaster applied to the outer surface of the asphalt coating.

2. A heat and sound insulating and plaster holding material comprising in combination a plurality of sheets of dry felt, said sheets being united by a layer of asphalt and with a layer of asphalt upon the face of one of the sheets forming a plaster holding surface.

3. Plaster holding material comprising in combination a plurality of sheets of flexible material, said sheets being arranged in overlapping relation, each sheet projecting be-' yond the edge of the contiguous sheet and said sheets being united by a layer of asphalt and a layer of asphalt upon the outer faces of said sheets forming plaster holding surfaces.

4. A plaster'wall comprising in combination a sheet of cellular material with a layer of asphalt upon the face thereof, and plaster applied to the outer surface of the asphalt.

5. Plaster holding material comprising in combination a sheet of unsaturated felt with a layer of asphalt u on the face thereof forming a plaster hol ing surface.

In witness whereof, we have hereunto set out hands, this 27th day of February 1926.
